To aZZ w/imm it'may com:

Be it known that l, *PATRICK J. Km'rmo. a citizen of the United States,residing at J-hicago, in the county'of Cool: anclState of Illinois, haveiii-vented certain new and useful improvements in Soft-F lrlarmuers,

of which'the following is a specificatioh.

My invention relates to hummersfanrl more oertieulz-irhi' to hammershaving. a soft end "which ma into the hammer hotly in which form it isfound that after the head has been used. and is b'a't'teretl mid the'ineta l of the threaded portion stretched, it is almost impossible toremove the head in order to insert a, new.

one. To avoid this difficulty, it has been suggested that the threads beomitted and a transverse openingbe mad in the hammer body j 11st belowthe head or removable plug, and a wedge inserted therein for (lrivingthe head out; but in this form the bottom of the plug is not seatedagainst the solid portion of the hammer, the result being that thehammer face becomes concave, and, for another consideration, a firm blowwith the full and unyielding force of the hammer cannot be given.Numerous other clisatlvam tages occur in the use of this construction.

It is the object of the present invention to overcome all objections ofthe kind mentioned, as Well as others, and to provide a hammer whichshall be simple'ancl cheap.

in n'ianufacture, "which will deliver the full effective power of anyhammerof the same size and Weight, which shall have a soft head, and oneWhich will remain in the. hammer during everylrmcl of service and whichshall be easily movable at any stage of Wear and which Willuot, byWedging action of the hammer head llZSBlif upon the hammer body, causethe body to expand and be rendered less useful, or capable of havinganother head. of standard size substitute-51' as occasion may require orsuggest.

In the accompanying" drawings forming: part of this specification]: haveillustrated a preferred embodiment of these improvements, theillustration being that of 3..

The hammer hotly 10 is pr'e lerablv loads of cast steel antl is providedeye ll for the accommodation ot' the woocleuilfiaw clle 12-.aASflE-Oiill ends of the hammer fillies tratecl are alike, it will benecessary to describe but one. The end of she hemm er body-is providedwith a recess 13 having the sides substantially vertical to theface 14.-

of the hammer body, said recess having a bottom 15 substantiallyparallel with the face 14:. Between the bottom 15 and the sides of therecess I prefer to leave a small fillet 17 for purposes of strength. Thehammer head is also provided with a slanting aperture or hole 16 leadingfrom the middle portion of the bottom 15 to one of the sides of thehammer body. The plug or heacl 17 is made preferably of copper, althoughit may be formed of lead' habbitt, or other of the softer metals,according: to the particular use for which it may be clesireol. Theportion 18 of the head 1'? is adapted to fit nicely Within the recess13, this portion being of such length asto seat itself firmly upon thebottoni 15. This beacl also car ries an extended portion adapted to seatupon the face 14 of, the hammer body. It will thus be seen that theentire projected area of the face of the hammer falls upon/ the solidhai mer body, except for the smallv area of the hole 16 in the bottom.15 of the head 1? thus fitting the recess 13 and being seated in themanner indicated. becomes Well fixecl Withmusa e and does not re direaware; v

by any of the usual means at the hands o the plug recess. I have foundthat the plug or i mechanic, such as a vise e1- ehisell In order toremove these heads quickly and easiiv, ehere'fere, I previde the hole16, giving aeeess to the hot-om of the plug. By insering a punching tooas 20, in the opening 15, and applying hammer blows to the exneseei endof the teal izhe head is chsledg' A an forced cut of the hmnmer body. 1prefee ably give punehing @001 a slanting face, as shewn, se that itwill engage the foe-$9.0m of the head in a way so prevent expendingthe'metel of the heeai The oblique disposifiion of the passages 15,together with lecation equafiy at opposite sieles of the eye 11,preserves the balance of the body, While the strength and "Weight of thebody are not mefieriaily reduced.

he inclination or slant of the aperture 16 and the slanting ace of thepmlehing tool 520 permit this too in adition in the pressure it exericson the head 17 to act e. wedge-between the hetom 15 of the recess andthe adjacent face of the head 17 to force the head out 01? the recess asblows ere serueh on the end of the punching we extending beyond orwithout. the aperture 16 I have shown afihe end of the hammer heiy andthe soft head as eeizsgenal in shape, hue
